Description
Technical field
The present invention relates to a kind of water hardness test fluid, especially a kind of aquaculture and Shui nationality total hardness of waterTest fluid and preparation method thereof and using method.
Background technology
The source of aquatic livestock and Shui nationality animal and plant very extensively, especially the latter's original producton location water body is hardSpend different. For a lot of animals and plants, suitable water body hardness be maintain its healthy growth mustWant condition. Thereby move part aquatic livestock and the especially high-grade Shui nationality of most Shui nationality animal and plant,In the breeding process of plant, often detect the hardness of breeding water body.
Traditional hardness detection method is eriochrome black T method, and this method exists operator in implementation processMember's technical requirement is higher, and testing procedure is too complicated, and test result need to be carried out formula conversion, and medicine is notThe drawback such as portable. There is no at present the Patents for aquaculture and aquatic animal cultivating field specially, phaseClose patent spininess for water for industrial use, relate to drug variety more, configuration step is more complicated, and test knotFruit still needs to convert by formula, or need to compare and just can obtain with colour table. Aquaculture and the Shui nationalityIndustry all will be tested a large amount of water samples and various water quality index every day, for the requirement of testing efficiencyHigher than the requirement to accuracy, in other words aquaculture and Shui nationality industry wanting the test of water body total hardnessSeeking Truth can obtain result intuitively, simple and effective measuring method and test fluid fast and comparatively accuratelyContribute to raise labour efficiency, save production cost.
Summary of the invention
The object of this invention is to provide a kind of fast and compared with Accurate Determining aquaculture and Shui nationality total hardness of waterTest fluid and preparation method thereof and using method.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of aquatic products and the Shui nationality are supportedGrow and use total hardness of water test fluid, in every 1000ml test fluid containing edta edta 3.13～6.25g, ammonium chloride NH4Cl30～60g, concentrated ammonia liquor 100 that mass percent concentration is 25%～28%～200ml, eriochrome black T 1～4g, surplus materials is pure water.
Preferably, in every 1000ml test fluid, contain edta edta 6.25g, ammonium chloride NH4Cl15.5g, the concentrated ammonia liquor 100ml that mass percent concentration is 25%～28%, eriochrome black T 1g, surplus materialsFor pure water.
The preparation method of total hardness of water test fluid for above-mentioned aquatic products and aquatic animal cultivating, comprises the following steps:
(1) take 15～30gNH4Cl and 100～200ml concentrated ammonia liquor are assigned to 500ml with pure water;
(2) take 3.13～6.25g edta edta;
(3) NH of (1) configuration for the edta edta (2) being taken3-NH4Cl solution is moltenSeparate;
(4) take 1～4g eriochrome black T, add the solution of configuration in (3), pure water is settled to 1000ml.
The using method of total hardness of water test fluid for above-mentioned aquatic products and aquatic animal cultivating, by changing ethylenediamineThe concentration of tetraacethyl EDTA in test fluid or change volume of water sample to be measured, adjusts the every 0.1ml of test fluidThe hardness number of representative, calculates water body total hardness according to the consumption of test fluid.
The present invention has the following advantages compared with existing correlation technique:
1, drug formulation composition is few, and preparing process is simple, facilitates batch production to produce.
2, easy to use, without using formula calculate or check colors with color board, can obtain result.
3, can meet within the specific limits the requirement to different precision.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail:
Aquatic products of the present invention and aquatic animal cultivating total hardness of water test fluid, contains second two in every 1000ml test fluidAmine tetraacethyl EDTA3.13～6.25g, ammonium chloride NH4Cl30～60g, mass percent concentration isConcentrated ammonia liquor 100～200ml of 25%～28%, eriochrome black T 1～4g, surplus materials is pure water.
Preferably, in every 1000ml test fluid, contain edta edta 6.25g, ammonium chloride NH4Cl15.5g, the concentrated ammonia liquor 100ml that mass percent concentration is 25%～28%, eriochrome black T 1g, surplus materialsFor pure water.
The preparation method of total hardness of water test fluid for above-mentioned aquatic products and aquatic animal cultivating, comprises the following steps:
(1) take 15～30gNH4Cl and 100～200ml concentrated ammonia liquor are assigned to 500ml with pure water;
(2) take 3.13～6.25g edta edta;
(3) NH of (1) configuration for the edta edta (2) being taken3-NH4Cl solution is moltenSeparate;
(4) take 1～4g eriochrome black T, add the solution of configuration in (3), pure water is settled to 1000ml.
The using method of total hardness of water test fluid for above-mentioned aquatic products and aquatic animal cultivating, by changing ethylenediamineThe concentration of tetraacethyl EDTA in test fluid or change volume of water sample to be measured, adjusts the every 0.1ml of test fluidThe hardness number of representative, calculates water body total hardness according to the consumption of test fluid.
Embodiment 1
Configuration of the present invention:
(1) take 15.5gNH4CI and 100ml concentrated ammonia liquor are assigned to 500ml with pure water;
